Have we uncovered an alternative Christmas tune?

The "Lion sleeps tonight" seems to be this machine audiences song of choice for 2018 despite never actually officially appearing in a this machine set...random or what?

Great craic as always at the Frigate with a recent heart surgery survivor (from now on officially known as Stitch) risking opening his wounds to attend and lead the heckling 😂

Just so you all know "I am Spartacus!"
